What is the best way to update my iPhotos into Aperture (re-import)

Question

I want to re-import my iPhoto Library into Aperture 2 to update Aperture but am nervous about "overiding" changes I've made with the photos - and all of the projects, books, albums, etc. - that have been made in the last year.
What is the best, safest, don't-forget-to-check-this-box way of updating your iPhoto Library into Aperture 2?
Do I just reimport the whole thing but check the box that says to ignore duplicates?
Thanks,

            ex.printStackTrace();
   System.out.println("I got it:" + password);
